Linux router MTU between 2 interfaces
Gotta question. Have a linux rotuter with 2 physical interfaces and a ipip tunnel. The one interface is connected to my isp, and the other is connected to my LAN. Routing is set up over the ipip tunnel to my office so I can route information between my office and my home.
The tunnel has an MTU of 1480 and connects via eth0, eth1 has an mtu of 1500.. Everything communicates fine, except when a packet is transfered that has a greater mtu than 1480 (unless I set all my machines at my house to have an mtu of 1480).. Any way to set the routers so they auto-fragment the packets if above 1480 and reconstruct them on the other side of the tunnel?
Thanks all
